* Spark plugs: Worn or fouled spark plugs can cause the engine to misfire, resulting in a rough start.
* Fuel injectors: Clogged or dirty fuel injectors can prevent the engine from getting the fuel it needs, which can also cause a rough start.
* Air filter: A dirty air filter can restrict airflow to the engine, which can lead to a rough start.
* Fuel pump: A failing fuel pump can cause the engine to get insufficient fuel, resulting in a rough start.
* Battery: A weak or dead battery can also cause a rough start, as it doesn't provide enough power to the starter motor.
* Starter motor: A faulty starter motor can also cause a rough start, as it doesn't turn the engine over properly.
If you're experiencing a rough start with your Jeep, it's best to have it inspected by a qualified mechanic to determine the exact cause and get it fixed.
